One of the best tips for making knitted beanies is to be sure to get an accurate head measurement and be able to knit to gauge. Beanies are close-fitting hats, so if the gauge is off, the result may look too loose. If a knitted beanie is too small though it's likely to feel uncomfortable to wear. Bulky yarn, or two strands of medium weight yarns, should be used for making knitted beanies so that the hats will have a firm structure as well as be warm. Double knitting or baby weight yarn can be used to make infant and toddler beanies.
For adults or children, the best way to determine the correct size for a fitted beanie is to measure the circumference of the widest part of the head such as how a hat would fit. A length of yarn can be used for the measuring before placing the strand against a ruler or tape to get the measurement in inches or centimeters. Once the head measurements are determined, patterns that include those sizes in knitted beanies can be created. The gauge of how many stitches and rows will equal a certain number of inches or centimeters should be followed even if the knitter must use needles that are either smaller or larger than the ones each beanie pattern recommends. It's obtaining the pattern's gauge that is important; not the size of the needles it takes each knitter to achieve it.
Skill level is an important consideration when knitting beanies. Although beanie construction using circular knitting needles prevents the need for sewing a back seam, this method is usually recommended for moderate level knitters rather than beginners. An easier method for knitting beanies is to use regular needles and work from the bottom edge to the top. When the beanie is about two-thirds complete, decrease stitches or whole rows should be started so that the hat tapers gradually to the top. Knitting two stitches together can be done for up to five rows at a time or stitch decreases can be worked evenly on each row in between regular knits or purls.
While beginning knitters should either purl every row of a knitted beanie or alternate that with a knit row to create the stockinette pattern, those with more advanced skills have more options. Cables on knitted beanies can give them a sophisticated look, while Fair Isle stitching adds a lot of color and pattern. Feminine lace beanies are another option for advanced knitters.
